The current trend in the market for cosmetic products is the creation of cosmetic products, including various coatings, with built-in natural substances. The main purpose of this graduation work is to develop a cosmetic coating with an application that will allow it to be used on a selected medium. To this end, the extract of field intestine was selected as an active substance, and psillyl in a protective colloid as a natural compound, capable of producing a gel in combination with the aforementioned extract. The property of the pronounced swelling of the psyll in protein colloid could thus be used to incorporate the extract of the aquifer into a gel-like structure for the purpose of relatively simple application of the healing / nourishing agent on the non-woven viscose carrier substrate or as electrospun fibers. As a source of natural active ingredients, a field pit is chosen as a rich source of silicon, which can be used as an integral part of the cosmetic coating, for example, reducing cellulite, reducing the visibility of age spots, facial wrinkles in a similar way. A great potential of proteinyl colloid-based textile coatings based on psyllium in combination with a field patch for cosmetics and care has been identified, as in vivo results, which were measured on test subjects, are extremely promising.

An environmentally friendly procedure, electrospinning, was used for the first time to prepare polysaccharide nanofibrous mats with incorporated olive leaf extract, with the unique property of releasing the active phenolic components in a prolonged manner over 24 hours. The developed electrospun mats were characterized using scanning electron microscopy, high-performance liquid chromatography and ultraviolet-visible spectroscopy for determination of free radical scavenging activity by 2,2-diphenyl-1-picrylhydrazyl, antimicrobial testing and release kinetics. Antimicrobial tests have shown that electrospun mats with olive leaf extract achieve reduction towards the tested microorganisms: Staphylococcus aureus (G+), Escherichia coli (G-), Enterococcus faecalis (G+) and Pseudomonas aeruginosa (G-), while the high antioxidant activity of olive leaf extract was preserved during the electrospinning procedure. Release of olive leaf extract from electrospun mats was mathematically modeled, and the release kinetics evaluation indicates the appropriateness of the Korsmeyer–Peppas model for fitting the obtained results of release ability due to erosion of polysaccharide nanofiber mats.
